In this paper, a novel hybrid ZVS resonant topology is proposed for PEV battery charging applications. The proposed charger architecture combines the advantages of SRC and LLC topologies while avoids their drawbacks in battery charging application. The circulating current in the magnetizing inductor is reduced, which helps to reduce the circulating losses. The peak current of primary MOSFETs are also reduced in comparison to the conventional LLC topology; this reduces the conduction losses from the MOSFETs and improves the circuit reliability. Moreover, turning off current of power MOSFETs are reduced, which reduces the switching losses associated with the turning off of MOSFETs. Simulation results based on designed 1 kW prototype shows 96.8% peak conversion efficiency.
